I have just received the results of some neurological tests I had done a few weeks ago and the Hospital is telling me that they suspect a "lesion on the ulna nerve" in my left arm (I am right handed) and that they "recommend surgery to further investigate the problem and, possibly, alleviate it at the same time". I have yet to discuss it with the surgeon, so I have no idea at present what sort of "odds" they are going to give me on the chances of curing it or, for that matter, making it worse. The symptoms I have been suffering from is waking in the morning with the second third and fourth fingers of my left hand "clenched" straight against my palm. The only way I can release them is to put my hand in warm water and massage it for a few minutes. Once I've done that, the fingers loosen up BUT my left forearm (from the elbow down) and all three fingers feel tingly all the time. Kind of a cross between pins and needles and the feeling you get if you hit your "funny bone" on something. I find that the most comfortable position for the second third and fourth fingers of my left hand is the position they are in when I wake and they seem to naturally go into that position when I am not thinking about it or concentrating on playing. It doesn't seem to affect the first finger or thumb at all. I am not playing any more or less than usual and the material I am working on is no more or less demanding than before, so I can't really see what has changed. I have been suffering with it for about a year now and it has taken this long to have it checked out. I was wondering whether anyone else had experienced anything like this and, if so, how successful the possible surgery is likely to be? I have to admit that I am truly terrified that they may do the operation only for it to get worse and for me to actually lose the ability to play. Any advice/reassurance/anecdotes etc would be very welcome.
